'Application filed May 2, 1918.

To all whom t may concern:

Be it known that I, HERMAN C. PRIEBE, a citizen 0f the United States of America, residing at Blue Island, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Underframing, of,which `the following is a specification.

This invention relates to railway carsand more particularly to that part referred to as the underframing for supporting the draft gear.

One of the objects of the present invention is to provide an improved underframing construction of such simple and compact arrangement as to be more `durable and reliable than the constructions in use prior to this invention. Another object is to lso position, arrange and connect the various elements and parts forming the underframe construction as to prevent relative longitudinal and lateral movements thereof under the shocks and strains to which the car is subjected particularly in the coupling and uncoupling operations. A further object is to provide a structure of the above general character which may be easily and inexpensively manufactured and assembled and permit the installation of draft gear of any desired type with a minimum amount of trouble.

Other objects will be in part obvious from 'the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more com pletely outlined herein.

To enable others skilled in the art so fully tc comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention,

drawings depicting a preferred form have been annexed as a part 0f this disclosure, and in such drawings, like characters of reference denote corresponding parts throughout all the views, of which:

Figure 1 is a plan and partial sectional view of such parts of the underframing as are necessary to fully understand the present invention; Y I

Fig. 2 is a side elevation of the parts Patented Japr. 29, i919.

Serial No. 232,028.

shown in Fig. 1 with the end sill in section;y

Fig. 3 is a sectional view taken substantially along the line 3-3 of Fig. 2; and

Fig. 4 is a sectional view takenV on the line -l looking in the direction 0f the arrows.

Referring now to the drawings in detail, 5 denotes a pair of separated longitudinally disposed members, preferably wooden beams, constituting the center sills of the car. These beams are embraced along the bottom and underside by angle irons 6 of L-shaped cross sections connected at their forward parts, that is, the left hand side in the drawings, with channel beams 7 forming the draft sills and at their rear parts or right hand portion, as shown in Figs. l and 2, with sub-center sills y8. Between the draft sills and sub-center sills 8 is a: space l0 within which is adapted to be mounted the transverse body bolster of the car. As this forms `no part of the present invention, it is believed to be unnecessary to show the same in detail having been described and claimed in combination in my prior Patent l:,tt1,253,187, January 8, 1918. Strengthening irons 1l are secured to the angle iron 6 above this point.

The forward or left hand `ends of the angle irons 6 are vprovided with relatively small vertically vdisposed abutments l2, as shown in Fig. 4, which are riveted at 13 t0 the angle irons 6 and are adapted to abut an end sill 14 extending across the end of the car above the draft sills 7. This construction increases the relative area of the main center sill at its point of engagement with the end sill to better take up the shoc :s and strains to which the underframing is subjected.

The end sill 14C must be held firmly in position against both relative lateral and longitudinal movement with respect to the other parts. It is upon this sill that the greatest strains are exerted because of the momentum of the weight supported by the center sills of the car in starting and stopping. Suitable bolts 15 are therefor provided which pass downwardly* through the end sill and registering holes in one or both of the flanges of the draft sills 7. These bolts may be of any desired type and may be provided with lock nuts 18 at either the top or bottom as desired for holding the parts in assembled position.

The inner or adjacent surfaces of the draft sills '7 are provided with malleable 'iron castings 2O provided with holes 21 registering with corresponding holes in the draft sill members through which transverse bars are adapted to be passed for supporting the draft gear, as shown in my above referred to patent. For the sake of clearness, the draft rigging has been omitted as it is of well known construction and forms no special part of the present invention.

It will thus be seen that the invention herein illustrated` and described'embodies a simple and practical construction in which the parts are so positioned and arranged as to allow maximum flexibility yet at the same time provide a most durable, reliable, and efficient construction fully capable of resisting all of the strains and shocks to which the parts may be submitted.

I/Vithout further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current lmowl edge readily adapt it for various applica tions without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.

I claim:

1. In an underframe construction, in combination, a main center sill composed of two separated beams, a draft sill associated therewith comprising two fianged 'channel irons adapted to be supported by the center sill members along their upper edges, l..- shaped angle irons on the adjacent sides of the center sill beams and securing the draft sill members to the center sill members, a

transverse end sill above the draft sill members and at one end of the center sill members, angle irons secured to each center sill member abutting the end sill, vertically disposed tie bolts passing through the end sill and flanges of the draft sill members adapted to prevent relative longitudinal and lateral movement of the end sill with respect to the draft sill members, and malleable iron castings secured to the vertical sides of said draft sillinembers for supporting the draft rigging. n

2. In an nnderframing construction, in combination, a main center sill composed of two separated beams, L-shaped angle irons covering' the Aadjacent and bottom faces of said beams, a draft sill comprising a pair of flanged channel irons supported by Q the center sill members along their upper edges, metallic members securing the draft sill to the center sill, and a transverse end sill above the draft sill members and at the end of the center sill.

3. In an underframing construction, in combination, a main center sill, composed of two separated beams, a draft sill comprising two flanged channel irons supported by the center sill along their upper edges, an end sill above the draft sill and at the end of the center sill, tie members passing through the end sill and draft sill, and malleable iron castings having perforations secured to the inner vertical sides of said draft sill members through which draft bars are adapted to be passed.

In testimony whereof I affix my signature in the presence of two witnesses.
